If you mean: 7xy-xy+3xy then by collecting like terms it is 9xy.
3xy - 3xy = 0
3xy
3xy and 2xy. You can see that 3xy and 2xy have something in common with each other. They both have xy and the end of them. Hope this helped.
3xy
-3xy is a monomial where x and y are variables and -3 is the coefficient of the monomial.If we know the value of y, we have to substitute it for y, and we say that -3(y-value) is the coefficient of x.
3xy - 3xy = 0
There are only the two terms, so 8xy
x=63xy-2/x39*x2y4/x69x2x6*y4
18x3y5 + 9xy3 - 3xy = 3xy(6x2y4 + 3y2 - 1)
3xy-4x + 15y-20 Sol: As there are no number are same. So -4x-3xy +15y-20 -------------------- -4x-3xy+15y-20
1,3,x,y,3x,3y,xy,3xy
3xy
3xy and 2xy. You can see that 3xy and 2xy have something in common with each other. They both have xy and the end of them. Hope this helped.
That refers to terms that have exactly the same combination of variables. For example, in 5xy + x2 - 3xy, the first and last term have the same variables, so they are similar. You can simplify an expression by combining such terms.
3xy + 3y2 = 3y (x + y)
3xy2z
This is clearer if you use fractional powers, at least for the intermediate steps. The fourth root of 32x2y2 is (32x2y2)1/4, or 31/2x1/2y1/2. In other words, the square root of 3xy.
